== Mii QR Code format ==

3DS Mii QR is a standard 57x57 pixel Level 10 High ECC QR code with 'Mii' logo in center (refer to [http://www.denso-wave.com/qrcode Denso-Wave Inc] web site for QR Code format specifications). It contains 0x70-bytes of binary data. 3DS seems to have a fully implemented QR-code decoder, as it can interpret such Mii binary data being encoded even in the smallest possible for that data size Level 6 Low ECC QR code. The data itself is encrypted with AES-CCM, xorpads can be determined from known plaintext here~~. It's unknown what is used for the nonce~~. The Mii Maker application uses the [[NS]] APT Wrap/Unwrap commands to encrypt/decrypt this Mii data.
